In my fitment experiences with 5.56 mags/AK variants.
Yugo M85/90/95 mags are AKM pattern and .850" at the front area.
Yugo M85/90/95 - will accept and cycle Weigers, Chinese, Romanian and Bulgarian waffle (tight) mags.
Chinese type 84- will not accept Weiger or Romanian or Yugo or Bulgarian
Romanian Md97- will not accept Chinese, or Yugo or Bulgarian
Modifications aside of course.
